In this paper firms may deviate from standard product specifications by investing in flexible production. In a two-sector general-equilibrium model that features consumer preferences with a desire for customization and in which the fixed cost of manufacturing production depend on the extent of flexibility chosen, we find that flexibility in production increases aggregate welfare. Moreover, we find that the symmetric equilibrium with positive (excess) profits welfare dominates the equilibrium with zero profits.  相似文献

This study investigates the coverage of solid waste management on 1142 websites maintained by companies, news media and non‐governmental organizations to validate an automated approach to content and language analysis. First, a frequency analysis of waste management terms sheds light on the breadth and depth of their environmental discourses, revealing that corporate and media attention to waste management is small compared with that of non‐governmental organizations. Second, an investigation of their attitudes toward waste management suggests that companies avoid negative information in environmental communication, unlike news media or non‐governmental organizations. Ultimately, an automated tool for ontology building is employed to gain insights into companies' shared understanding of waste management. The ontology obtained indicates that companies conceptualize waste management as a business process rather than framing it from an ecological perspective, which is in line with findings from previous research.

I reconsider the implementation of efficient cost and quality efforts when health-care providers may refuse services to consumers, and introduce a mechanism that is a combination of prospective payment and cost reimbursement. Conditions are derived for the prospective payment level and the margin above cost reimbursement for the implementation of efficient efforts.  相似文献

Although a good deal of empirical research is available on the measurement of turkey body weight gain response to fat supplementation, none has attempted to study the economics of optimizing fat level in turkey diets. This study focuses on deriving the optimal fat level in turkey diets. The methodology used should also apply to any nonruminant species (swine and poultry).  相似文献

Targeted poverty investments and economic growth in China   总被引:1,自引:0,他引:1  
In the mid-1980s, the Chinese government launched its ambitious poor area development policy, which was centered around a series of grant, credit, and Food-for-Work programs. Ironically, for the remainder of the 1980s rural poverty remained at about 90 to 100 million, or approximately 10% of the rural population. The lack of progress cannot necessarily be blamed on ineffective poor area policies, since much of the agricultural economy was mired in a deep recession between the mid-1980s and the early 1990s. By the mid-1990s substantial additional poverty reduction had been achieved. Even in the late-1980s, farmers in many poor counties did better than the national average in terms of income growth. After accounting for the effects of macroeconomic elements, what factors can help explain the differences in performance among poor regions and between poor areas and rich ones? Can part of these differences be accounted for by poor area policies, in general, or by the way local and regional officials allocate their poor area investment funds, in particular?The overall objective of this paper is to analyze the effectiveness of Chinese poor area policy. Specifically, the paper seeks to meet three objectives. First, we want to understand the evolution of poor area policy since the mid-1980s, trying to deduce the true goals of central and regional poor area officials, as well as how these policies have been implemented in the provinces. Next, we want to understand the magnitude and scope of investment into poor areas, and examine if changes in these policies have affected the uses of the investment funds. Finally, we want to determine the effectiveness of the investment of poor area funds, analyzing which types of investments have generated growth, and which ones have not.  相似文献

Discoveries in the physical and biological sciences suggest that intelligence is widely distributed throughout the universe. Before long, either we will decide that these discoveries have pointed us towards a false conclusion, or we will obtain undeniable evidence of extraterrestrial life. After finding one extraterrestrial society, we are likely to discover others and, in this manner, become a part of the “Galactic Club”. Following the “slow track”, an initial encounter will lead to accelerated search efforts that will put us in touch, one by one, with additional societies. Following the “fast track”, our initial contact will be with an affiliate of the Galactic Club, and this society will give us instant access to other members. The physical constraints imposed by interstellar distances, coupled with our understanding of large social systems, suggest that the Galactic Club will be large, stable, slow-paced, and exert only loose control over its members. The two tracks have different implications for managing initial contact, protecting our security, knowledge transfer, handling culture change, and preserving our identity.  相似文献

In this article I claim that the Nobel Prize in Economics has not only set the economics discipline on a path‐dependent trajectory, but is itself an apotheosis of a development of what I would like to refer to as ‘the statistical turn in economics’. The case of Jan Tinbergen illustrates the argument and sketches the stages within the statistical turn in economics. The Nobel Prize in 1969 acknowledged this character of economics, and justified the continuation of this approach for the generation to come.  相似文献
